Lords Truscott and Taylor are first to be suspended from Lords since 1643

Two Labour peers will be suspended from the House of Lords until the autumn after being found guilty of offering to try to change the law in return for money.

An investigation into the so-called “cash for amendments” affair has concluded that Lord Truscott, a former energy minister, and Lord Taylor of Blackburn, broke Lords rules saying that peers must “always act on their personal honour”.

They will be the first peers to be suspended from the upper house since 1643, when parliamentarians removed those peers who had taken up arms in support of King Charles I.

Two other Labour peers implicated in the affair, the former MPs Lord Moonie and Lord Snape, have been cleared of any wrongdoing but ordered to apologise to the Lords for “inappropriate” conduct.
